Add ListToggle and built-in search filtering to ResourceControls, move Export/Clear buttons to HistoryListPanel

ResourceControls now manages its own search state internally and filters
all three accordion sections (URIs, Templates, Subscriptions) by name
and URI. Added ListToggle to expand/collapse all sections. Moved Export
JSON and Clear All buttons from HistoryControls sidebar to the
HistoryListPanel header for better proximity to the data they act on.
